In today’s digital age, the performance and reliability of web applications are more crucial than ever. With users expecting fast, seamless experiences, ensuring your application work flawless across all browsers and devices is a must. That’s where Cypress comes in. It’s not just a tool; it’s a complete solution designed to make testing less of a chore and more a part of the development process.

In this blog, We’ll explore the core features of Cypress and how to use this powerful tool to write tests and ensure your web UI runs flawlessly. Whether you’re a developer looking to write efficient tests or a QA engineer seeking a reliable testing framework, this blog has valuable insights for you.

Introduction to Cypress

Cypress is a cutting-edge solution for web application testing needs, offering a comprehensive suite of features like automation, debugging, and real-time feedback.

This tool stands out for its ability to execute tests directly in the browser, offering a streamlined testing workflow for both developers and QA engineers.

Built on Node.js and using JavaScript, Cypress simplifies the testing process with easy-to-understand commands and smooth integration.

With Cypress, writing, configuring, running, and debugging tests becomes effortless, making it the preferred choice for efficient and effective web application testing.

Why Cypress?

End-to-end (E2E) testing plays a vital role in achieving the goal of ensuring the quality and functionality of your web application, and Cypress has emerged as a popular choice for developers and testers alike. But what makes Cypress stand out from the crowd? Let’s dig into the compelling reasons why Cypress deserves a spot on your testing framework shortlist:

Main Features of Cypress

Time Travel: Cypress captures snapshots during tests, allowing you to review what happened at each step by hovering over commands in the Command Log.

Debuggability: Cypress makes it easy to debug failing tests by incorporating familiar tools like Developer Tools. You’ll find clear error messages and paths that help you quickly pinpoint and fix issues.

Automatic Waiting: Cypress intelligently waits for commands and assertions to finish before proceeding. This eliminates the need for you to insert manually waits or sleeps in your tests, saving you time and effort.

Spies, Stubs, and Clocks: Cypress lets you change how functions work, what servers say, and how timers run. This is handy for testing small parts of your code with features like spying on functions, changing responses with stubs, and controlling time with clocks. It’s especially useful for API and unit testing.

Network Traffic Control: Cypress enables easy management, stubbing, and testing of network traffic without relying on your server, giving you full control over network calls.

Consistent Results: Cypress utilizes its own testing framework instead of relying on Selenium or WebDriver. This approach ensures fast, reliable, and flake-free tests.

Screenshots, Videos, and Test Replay: Cypress automatically captures screenshots on failure and records videos of your test suite. Test replay facilitates easy debugging with zero-configuration setup.

Cross-Browser Testing: Cypress allows you to run tests locally or in a Continuous Integration pipeline on various browsers like Firefox and Chrome-family browsers.

Smart Management: Cypress makes it simple to run many tests at once(parallelization), focus on fixing the ones that didn’t work, and stop tests if something goes wrong to get quick results.

Prerequisite Steps for Setting up Cypress Environment

In this blog, during the practical demonstration, we utilized the following versions for the respective libraries and applications:

1. Visual Studio Code version: 1.88.1
2. Node JS version: v20.12.2
3. Cypress version: 13.7.2

Download & Installations
1️⃣ Download Node.js and install Node.js in your system

2️⃣ Download Visual Studio Code and install VS code in your system

3️⃣ Install Cypress

Launch Visual Studio Code and open the integrated terminal to install Cypress using the following commands:

• Type ‘npm init’and follow the prompts as asked or just press Enter to continue. It will create a package.json file.

• Then type ‘npm install cypress –save-dev’ and press Enter.

4️⃣ Launch Cypress:
Launch Cypress by executing the command:

• npx cypress open

This will open Cypress in headed mode. Select ‘E2E Testing’ and then click on “Continue” on the Configuration files screen and Congratulations! Your Cypress project is now prepared to begin your first test.
